I'm trying to identify a sci-fi cartoon / animated film from late 70's / early 80's. I remember very little to be honest, but here goes:

It had a short, chubby chap in a white space suit and a bunch of taller minions in identical but black suits. Both had red eye pieces I think (or possibly slit visors) and looked a little like Death Star gunners from Star Wars, though their helmets were stretched vertically. They were on some sort of moon facility and I remember the white-suited chap being sad when the others left.
